Definitions

  • the invention relates to an underground structure for erection in an underground made of firn or ice.
  • the snow or ice ground is generally not dimensionally stable, but is subject to constraints from movement as glaciers or ice shelves, which lead to deformations (pressures, strains, twists and settlements) for which the building is normally not designed and their static and constructive Consideration is extremely expensive.
  • the invention has for its object to provide a structure and to find a construction that is insensitive to wind loads, snow accumulation and deformation of the ground.
  • this object is achieved in that a flat roof construction resting on supports is adjustable in height such that its upper edge is always essentially at the same height as the surface of the snow or ice.
  • the invention proposes to arrange devices for height adjustment of the roof structure on the supports, between supports and roof structure or below the supports.
  • the supports can preferably be connected to the roof structure and foundations via joints.
  • the supports are horizontally displaceable at their lower end.
  • the invention proposes to divide the roof construction into several segments by arranging joints.
  • roof structure on its edge adjacent to the firn or ice with devices that make it possible to pull the edge back from the firn or ice when adjusting the height of the roof structure.
  • the outer surface of the roof edge is provided with a coating which keeps the friction between the roof edge and the existing firn or ice low.
  • the invention further proposes to let the outer surface of the roof edge run obliquely outwards from the bottom upwards.
  • roof edge can be designed as a hollow body which can be acted upon by a heating medium via pipelines.
  • a segment of the roof structure connected to the rest of the roof structure can be raised to such an extent that an underneath ramp is accessible.
  • side walls can be connected to the raised roof segment along the length of the ramp.
  • the solution according to the invention consists in arranging an underground building consisting of roof construction and supports in such a way that the roof surface is always or gradually changing due to the height adjustment Terrain surface can be adjusted.
  • the height adjustment is carried out on the supports; it can be done for the whole roof at once or for individual roof sections one after the other.
  • the roof edge is provided with a covering that has a low coefficient of friction, or it is heated.
  • the roof edge can also be designed to be movable in relation to the actual roof and be pulled back by the firn or ice before the lifting process. Combinations of the features described are possible as required.
  • the roof edge can also be arranged obliquely or vertically as required.
  • the walls and floor of the building are formed by the upcoming firn or ice. Due to its high shear strength, this subsurface can be regarded as sufficiently stable in polar regions. The bulging of the walls towards the room caused by creeping as well as the bulging of the floor in the building caused by reduced load can be taken into account by removing it with a suitable device.
  • a sufficient seal between the edge of the roof and the existing subsoil will result from blowing snow by itself after a lifting process. This process can be accelerated by the targeted introduction of snow.
  • the supports are not extended during the lifting process, but are either placed back on their old foundations after inserting an appropriate intermediate layer of snow or other materials or - with the loss of the old foundations - on new foundations. Settlements or uplifts in the subsurface, even if they are uneven, can be compensated for at any time by traversing with the lifting device.
  • the construction will not suffer any static disadvantages in the event of deformations, especially also when the substrate is deformed horizontally. If an inclination of the supports from such deformations disturbs or is not accepted, the supports can be moved horizontally on their foundations at their lower ends, if necessary after provisional interception.
  • the construction can easily be expanded to the effect that one or more sides of the roof can be temporarily raised so far that vehicles can enter the underground building via a ramp arranged under the edge of the roof.
  • the roof side to be lifted can be connected to the rest of the roof in an articulated manner, and walls can be connected to the liftable roof part at ramp length, which are raised when the ramp cover is opened and make it difficult for the ramp to drift from the sides.
  • the space 1 occupied by the building is obtained by excavating the upcoming firn or ice, the current surface of which is identified by the line "s-s".
  • the walls 2 of the building correspond to the walls of the building pit, and the floor 3 of the building pit corresponds to the floor of the building.
  • the floor is raised during the later lifting of the building by backfilling 4 to the required level 3 '. With the usual rigidity of such a subsoil, excavation can take place both before and after the roof 5 is installed.
  • the building room 1 can not be heated above about -3 ° C for obvious reasons, but can be directly to Example for storage purposes or as a garage.
  • Heat-insulated buildings 6 for residential and work purposes can be used without restriction if suitable heat is provided for the heat that drifts outwards.
  • the roof consists of a suitable dense roof skin 7 with or without thermal insulation 8 in a horizontal or inclined design and the supporting structure 9 located underneath, which transfers the loads and roof weights to the supports 10.
  • the number of supports in cross-section (two in the drawing) is arbitrary and only determined by the purpose of the building.
  • the supports have as much distance from the walls as is necessary, depending on the method used for the notification of the walls in the case of deformations from circles, but at least so much that a man can move freely there.
  • the supports stand on surface foundations 11, which remove the support loads into the ground. They are articulated at the base 12 and at the head 13 to foundations or roof. The foundations in the drawing have already been extended by the intermediate structure 14 by the intermediate structure 14 after previous lifting operations.
  • the original building floor 3 was at the level of the dashed line "u-u"
  • the lifting device 15 on each support is preferably arranged near the floor in order to be more easily accessible and can work mechanically or hydraulically according to one of the known methods.
  • the articulated support 12 at the foot of the support can be shifted horizontally in any direction on the foundation surface by a suitable device 16 and locked there.
  • the roof edge 17 is articulated to the roof by a joint 18.
  • the joint is protected against thrust from snow or ice by a projection 19 of the roof.
  • the lower part of the roof edge can be rotated about the joint 18 via a suitable conventional construction 20, for example by means of spindles or hydraulic presses, and can thus be adjusted horizontally.
  • the joint 18 can be secured against snow flying by a flexible sealing skin 21 between the roof and the edge of the roof.
  • the outer surfaces 22 of the roof edge are preferably coated with a low-friction material.
  • the roof edge 17 is suspended at the top in the roof by means of the suspension 23 and, at the top and bottom - and can be moved together or separately - horizontally with respect to the roof by means of suitable conventional construction elements 24.
  • the roof edge 17 can also be made rigid in a vertical position or, as shown, in a slightly inclined position.
  • a heater 25 for example with warm air, works for the safe detachment of the roof edge from the surrounding firn during the lifting process, if the roof edge is designed accordingly as a hollow body 26.
  • FIG. 4 shows how a cutting edge 27 can be arranged on the edge of the roof above the roof edge, in order to more easily shear off the firing material above the roof up to the surface s-s when it is lifted.
  • the building does not differ from the cross section, but the kinema are at the corners table conditions with movable roof edges.
  • the joints 28 enable the roof to be lifted in sections and are protected against the passage of snow or melt water by a flexible or movable joint cover 29.
  • a similar joint, but provided with a joint or joints 30, is also arranged in the roof at the beginning of the ramp 31.
  • the roof in the ramp area 32 can be raised so far that vehicles can use the ramp.
  • the lifting devices 33 on the supports 34 in the ramp area allow corresponding lifting heights.
  • the sides 35 between the roof and the surface ss can be protected against the ingress of drift snow by a suitable wall construction, for example by a suitably tailored windproof cloth.
